In 1953, Ilmari Tapiovaara received a traditional African chair from the Congo as a present from a friend. He got very excited by the structure of the chair, where the seat/back leg element is pushed through the back rest/front leg part, thereby locking in to the solid robust seat. Tapiovaara designed numerous versions based on the same theme, both from tubular steel and wood.
